The IEA conducts a broad range of transport research and analysis, focusing on ways in which countries can improve the sustainability of their transport systems. Policy advice is given to governments on the effectiveness of implementing advanced technologies, improving fuel efficiency and shifting to lower carbon fuels and transport modes.

Our focus

Getting transportation on track to meet the IEA 2 Degree Scenario targets requires implementing a broad set of policies, summed up as “Avoid, Shift, Improve”. The IEA helps further this transition by analysing technologies and transport systems that can be developed and adopted by countries to reduce dependence on oil and emissions of greenhouse gases. This work also enables reductions in air pollution, road fatalities and congestion, while improving passenger and freight transport access.

Fast facts

  • 93%of final energy consumption for transport uses oil products, the least diversified sector
  • 28%the amount transport energy and CO2 emissions have increased since 2000
